In Megabonk, damage bonuses don't simply "add together." They are grouped into brackets: bonuses within the same bracket combine additively, but different brackets multiply with each other. Understanding this system is the key to massive DPS.
⚔️ GAME MECHANICS • DAMAGE FORMULAMegabonk's damage system uses 8 independent brackets. The rule is simple:
Having +50% in Bracket A and +50% in Bracket B gives
1.5 × 1.5 = 2.25× total damage. But stacking +100% in just
one bracket gives only 1 + 1.0 = 2.0×. Spreading bonuses across
brackets always wins.
Below is the complete mapping of every known damage bracket and its associated items:
Your Tome's damage multiplier. Acts as an independent multiplier on all weapon damage.
SOLO BRACKETCharacter-specific damage bonus from Noelle's passive ability. Multiplies independently.
CHARACTER-SPECIFICDamage bonuses specifically against elite enemies, from multiple sources:
Damage multiplier from the Corrupted Sword weapon/modifier. Exists in its own bracket.
SOLO BRACKETBracket 4 (Main "Damage %") has 11 items — the most of any bracket. Because items within the same bracket only add together, stacking many items in this bracket has diminishing returns relative to investing in other brackets. A single item in a solo bracket (like Speedy Boi or Giant Fork) can be more impactful than adding another item to the main bracket.
Let's compare two scenarios to show why bracket diversity matters:
Scenario A spreads +100% across 3 brackets → 2.37× damage
Scenario B dumps +100% in one bracket → 2.0× damage
That's 18.5% more damage just from bracket diversity!
The gap gets even wider as you stack more bonuses.
Items that sit alone in their own bracket (like Speedy Boi, Giant Fork, Corrupted Sword) are extremely efficient because their bonus multiplies independently with everything else in your build. Even a small bonus in a solo bracket can outperform a larger bonus in the crowded main bracket.
The Main "Damage %" bracket already has 11 items competing. Each new item you add there only contributes additively alongside all your existing bonuses. Instead, look for items in Brackets 1, 3, 5, or 8 to create multiplicative synergy.
Your Damage Tome choice is critical because it's always in its own bracket. A tome with a strong damage multiplier effectively multiplies ALL your other item bonuses. Choose your tome wisely — see our Best Tomes guide.
For boss-focused builds, remember that the Elite Damage bracket (Chaos Tome, Dicehead passive, Shrines) multiplies after all other brackets. This makes it especially powerful as a final multiplier on top of an already optimized build.
Damage Brackets are groups of damage bonuses that interact differently. Items inside the same bracket combine additively (add together), while different brackets multiply with each other. This means spreading bonuses across multiple brackets yields significantly more damage than stacking them all in one.
There are 8 known Damage Brackets: Damage Tome, Noelle's Passive, Flat Damage Upgrades (Gym Sauce / Brass Knuckles / Idle Juice), Main Damage % (11 items), Speedy Boi, Elite Damage (Chaos Tome / Dicehead / Shrines), Corrupted Sword, and Giant Fork Megacrit.
Because brackets multiply together. Having +50% in Bracket A and +50% in Bracket B gives 1.5 × 1.5 = 2.25× total damage. But stacking +100% in just one bracket gives only 1 + 1.0 = 2.0× total damage. The multiplicative effect always outperforms pure additive stacking.
Critical hits are applied after the full bracket calculation. The formula multiplies your final bracket-computed damage by (Number of Crits × Crit Damage Multiplier). This means crit builds benefit enormously from having strong bracket diversity underneath.
Yes, but only additively — they both sit in the same Main "Damage %" bracket (Bracket 4). If you have Boss Buster (+15%) and Tactical Glasses (+20%), that bracket's total is +35%, not 1.15 × 1.20. To get multiplicative synergy, pair them with items from different brackets.
